Lucerne (Medicago sativa) is a nitrogen fixing legume commonly known as alfalfa. It is valued for its drought tolerance, high yield, protein content and digestible fibre and as such makes good forage for ruminants. This document was compiled as part of the Better Returns Programme to provide best practice advice on growing and feeding lucerne to cattle and sheep. It describes various options for growing, picking and preparing sites, and selecting the most suitable variety of lucerne. It also describes establishment, fertiliser use, and management of sward height, pests and diseases, and weeds. Finally, it outlines how to conserve cut lucerne in either clamps or bales, and how best to graze and feed to livestock. It provides useful guidelines, tables of information, and case studies throughout. The document concludes with several research findings which suggest lucerne may support increased animal performance.
